T0 all wlwm zt mag; concem:

Be lt known that I, JOHN B. BIRGH, a subject 0f the King of Sweden, residing a1: Chicago, in the county of Oook and State of Illinois, have invented certain new a.nd useful Improvements in Koller Bearings, 0f which the following is a specification.

This invention relates, generally, to improvements in anti-friction bearmgs, but has partioular relation to the roller bearing type er dass ofsuch bearings, and oonsists in certain novel fea.tures and peculiarities in the construction, arrangement and combination of the various elements 01' parts thereof, as Will be hereinafter m0re fully sei: forth and specifinally claimed.

An im rtant object of the present invention, is t e rovision of a roller bearing in which *the arts thereof am so made arranged anal co-operating With one another as to enable them to be operatively assemb-led in a mach shorter ti1he a.nd more readily than has 'heretofore been generall acc0mplished.

Another object is t0 provi e a roller bearing of high efliciency in performing the functions of anti-friction roller bearings heretofore in generell use, and in addition thereto, to aflord means whereby load cmrying rollers only am e-mployed in connection with the retaining members thereof, thehusual spaoing rollen; being dispensed wit A still further object of the invention is the rovision of means to take ca.re cf 01' carry side thrusts of the Parts anal to reduce to a. minimum noise inc1dent to the operation of the various parts of the bearing.

Furthermore, the invention contemplates the rovision of a, bearing in which the rollers thereof will have uniform and simultaneo-us bodily as well as individual movements.

Other objects and advantages of the invention will become apparent. from the following description and explanation.

In the accompanying drawing, which serves to illustrate an embodiment of the invention,

Fig. 1 is a face view partly in elevation and partly in section 0f the bearing, showing the arts thereof in their operative positions.

Fig. 2 is a, greatly enlarged se;ctional view tanken on line 22 of Fig'. 1 looking in the direction indicated by the arrows.

Fig. 3 is a, side view 0f the bearing with' the keeper rings f0r the rollers removed, showing by continuous lines the position 0f the parts in the first step of assembling the same and by dotbed lines the second 0r following step in said operation, and

Fig. 4 is an enlarged fragmental sectional V18W similar t0 that shown in Fig. 2 and taken 0n the same line bul: with the roller kee er rings omitted.

orresponding numerals 0f reference rgfer t0 like parts throughout the different V1BWS of the drawing.

The reference numeral 7 desi ates the guter relgaining member er ring 0 the bear- 1pg, wh1ch may be made 0f any suitable s1ze und material, but is preferably made 1n the form 0f a ring, although if desired, 1l; may have its outer portion of other shape than circular. The inner surface 01' periphery of the ring 7 is inclined fromeach of its e-dges toward the outer surface cf the ring but said inclined portions terminate at their inner ends short of the medial line between the edges of the ring 7 as is clearly shown in Figs. 2 and 4 of the drawings. Between the inner ends of the said inclined portions the ring 7 is provided with an annular inwardly extended. rib 8 which has its sides outwardly inclined and bv preference at an obtuse angle to each otl1er. By this arrangement 01' construction it is obvious that the ring 7 will have 0n each side of tl1e rib 8 thereof an annular groove 9, the Walls 0f which unite the inner ends of the portinns inclined from the edges of the ring 7 with the unter ends of the inclined walls cf the rib 8 of said ring.

The inner retaining member 0r ring 0f the bearing is indicabed by the numeral 10 and may be made f any snitable size, but by preference of the same width as the outer r1ng 7, and is normally concentrically 10- cated in said outer ring but spaced therefrom. The inner ring 10 which may be suitably mounted. on a journal 01 axle, has its unter periphery inclined outwardly from its medial line between its edges t0 points near its edges, at which points the ring 10 is provided with peripheral recesses 11 each having an annular shoulder 12 disposed at right angles to the floors 0f said recesses.

From the foregoing and by refrence artioularly 130 F ig. 4 0f the drawing, lt wi l be understood and seen that while the inclined portions leading from the edges of the outer ring 7 and bhe inclined portions leading from the medial 1ine of the ring 10 am in clined in the same direction, yet it will be understood that the inclination of said parts am not looated in parallel planes, but are so disposed that the space between the coinciding inclined portions of the inne-r and outer rings a1e wider near ihe innex portions of said inclined Walls than ab their 0uter ends..

By this arrangement an annular spac'e having outwardly inclined and slightly coutracted Walls is rovided in which a plurality of anti-frict1on rollers 13 are located in a pair of rows as will be readily understood by reference to Fig. 2 of the drawing. Eaoh of these rollers by preferenoe has its inner end cone-shaped as ab 14, und its opposite end diametrical. Euch of1zhe rollers 13 is tapered from its inner portion or end to its outer end bo correspond with the ta ered space between the outer retaining ring and the inner retaining ring 10 between which the rollers are located. A pair of keeper rings 15 and 16 of a size to fit between the outer retaining ring 7 and the inner retaining ring 10, preferably, without contacting with the former as will be understood by reference t0 Fig. 2 of the drawing, are employed 10 fit loosely at their inner edges in the rex:esses 11 0f the retaining ring 10 und against the shoulders 12 thereof f0r the purpose of assisting in holding the rollers 13 in spaed relation. The keeper rings 15 and 16 are united and held in spaoed relation ab the edges of the retaining rings 7 and 10 between which they am located as above stated, by means of a number of bars 17 which am by preference secured'by means of riveting them ab each of the-ir ends in openings as at 18, see. Fig. 2, after the xollers 13 have been properly spaoed and said bars have been placed one between each pair of said rollers.

In order to assemble the arts of the bearing, th e outer'retaining member or ring 7 may be plaoed in ab0ut the position shown in Fig. 3 of the drawing, when a gurality of the load carrying rollers 13 may placed in a pair of rows 0n the inner surface of the said retaining rin with their conical ends 0f each pair of ro ers in contact with one another und with their inner peripheral ends or e'dges in contact with the inclined wa1ls 0f the rib 8 of said retaining rin The arrangement'of the rollers in the rst step of assembling the arts, is shown in Fig. 3 of the drawing, in which view it will be seen und understood tha.t the inner retaining ring or member 10 is then planed eocentrically within @he outer retaining ring 7 as shown by contmuous lines in sa.id figure, when by ca.using the inner ring 10 to assume the dottd 1ine osition shown in Fig. 3, it is manifest that the rollers 13 oan be moved between the inner a.nd outer retaining members und properly spaed. When the rollers am thus arranged, the bars 17 which perform the functions of spacing the rollers, as well as that of uniting the keeper rings, are then extended betweenthe spaced rollers 13, when by inserting the keeper rings 15 and 16 between the retaining rings 7 and 10 afi each edge thereof, the ends 0f the bars 17 may be caused '00 enter the openings in the keeper rings where said ends may beclinched o1 riveted, thus efl'ectually holding the bearing rollers in s .aoed relation and in transverse1y dispose pairs.

When the Parts am thus assembled, it is apparent tha.t by Teason of the novel and peculiar construction of the adjacent surfaces of the innen am]. auer retaining members anti of the rollers, as we1l as by reason of the cross-sectionally angular rib midway between the edges of the unter retainixig ring, side thrusts of the parts will be properly taken care of and that as the rollers 13 contacb with 0r travel on the inclined adj acent Slll'f3S cf the inner und. outer reta1rling members as Wall as against the inclined walls of the annular rib of the outer retaining member, a noiseless, eificient, and substantially frictionless bearing will be aifordad, in which the entire number of rollers will have a, uniform movement as well as individual 01' independent movement.

By providing the outer retaining ring 7 with the annular rib 8 midway between the edges 015 said ring, and by providing said rib with its side walls disposed ab angles bo or xe another as well as at angles to the in clined portions of the inner periphery of the ring 7, it is manifest that the when the rollers 13 areplaced in the positions shown in Figs. 3 an 4: of the drawing, the edges onlv of the inner peripheral ortions of the sai rollers will contact witii the Walls of the rib, thereby providing stops to prevent the rollers from either side 0f the rib being extended too fa.r bowards the other side of the rib and also by this arrangement it is obvious that frietion will be reduced to a minimum incident to the contact between the inner peripheral edges of bhe rollers and the walls of the rib, thereby preventing heating 0f the parts. The. peculiar con struction and r'elation of tha rib with respect to the inclined inner portions of the r1ng 7 further provides 'means by which the inner surface of the ring 7 can be ground when neoessary, without. disarranging the relation of the inclined parts of the inner periphery of the ring 7 with respecb to the angular walls of the rib 8, for it 1s a:pprirent that the 0oves 9 will receive the grmding bool in t e o peration of grinding the surfaca of said rmg.

Ha.ving thus fully descfibed my invention, what I claim as new and desire to secura by Letters Patent is- In a, roller bearing, the combination with an unter retainin r1ng havingits inner periphery outwardfi inclined from its ed es to points neai each side of its medial hne between said edges and provided on S2Lid line with an inwardly exgnding annular rib having inclined side walls, of a phirality of opposite-ly tapexed rollers located on the inner surface of said ring in pairs, said rol- 10 lers haVing cone-shapeiends at the larger E0rtions thereof, and an inner retaining ring aving its unter peripher outwudly inclined in such manner wit relation bo the inclined portions upon said unter rin and said annular rib so that bhe coneaped ends 0f each pair of rollers are held in con' tact with each other upon one side 0f the apices of said cbnes and edge oontact with the rib upon the opposite side of said apioes.
